Hairdressing professionals frequently encounter formaldehyde, a component found in hair products that are known to have various toxic effects on the human body, including alterations in the sense of smell. Methods: A total of 32 hairdressing volunteers exposed to formaldehyde and 32 non-exposed volunteers matched for age, sex, education and smoking status underwent the University of Pennsylvania Smell Identification Test (UPSIT<sup>®</sup>). Results: The findings demonstrated a decrease in UPSIT<sup>®</sup> olfactory test scores and a higher degree of olfactory loss among hairdressers exposed to formaldehyde (mean UPSIT<sup>®</sup> scores: 30.6 vs 35.1, p Conclusion: Occupational exposure of hairdressers to formaldehyde is associated with diminished olfactory function. Education approach and promotion of personal protective equipment usage should be encouraged.展开更多

A 76-year-old man had idiopathic anosmia of 2-year duration. Four months before consultation, he began to have drooping in the right upper eyelid along with muscle soreness,distension, and pain in the nape. His tongue was dark-red with a thin and white coating; his pulse was wiry and slippery. According to Traditional Chinese Medicine, eyelid drooping and anosmia are the main signs of liver constraint and spleen deficiency. In Western Medicine, the diagnosis was ocular MG and idiopathic anosmia. Our patient, along with the literature, suggests that anosmia may be an early symptom before MG. MG accompanied by anosmia could be a special subtype of MG according to antibody production and symptoms.展开更多
